IMPROVEMENT lN TOOL-HANDLES.

Specification forming part of Letters Patent No. 124,443, dated March1;), 1872.

, hereby declare the followingto be a full, clear,

and exact description of the same, reference being had to theaccompanying drawing, in Which- Figure l is a perspective view of myinvention. Fig. 2 is a longitudinal section through the handle of thesame. Figs. 3 and 4 represent modifications of my invention.

My invention relates to a method of attaching cutting-blades to theirhandles, so that said blades may be adjusted at any desired lateralangle to the axis of the blade, to enable the blade to strike in oneplane while the handle is oblique thereto.

That others may fully understand my invention I will particularlydescribe it.

A is the blade, which is represented as a chopper in Figs. l and 2. Itmay be forged entire, though I nd it advantageous to make the same ofsheet-steel set upon a cast-iron head, b, as shown. When so made thehead b is constructed with a shoulder or ridge, a, against which theupper edge of the blade rests. This shoulder receives the stress of theblow when the chopper is in use, and relieves the rivets which unite theblade and head from the shearing strain. The head b is constructed witha shank or neck, C, which is Ycurved sidewise so as to set the blade offfrom the handle a little way, and by that means objects may be avoidedwhich would otherwise obstruct the handle during the use of theimplement. The upper end of the neck C is expanded to form a broad fiatdisk, c, and thereby secure a firm bearing against the handle, toprevent displacement in any direction. At the end of the handle D Iplace a strong cast-iron socket, E, having a flattened end, c, toreceive thepdisk c, and the two are held together by a screw-bolt, F,which passes through the head e and enters -a female screw in C. Thepart c is surfaced with'a suit-able tool, and is recessed slightly, asshown. The disk c on the head G is likewise surfaced, and fitted to therecess in thc part c, so that no shearing strain can effect the bolt. Bythe arrangement and construction of parts described above, greatstrength and rigidity are secured. In place of the choppingblade A, acutting-blade, G, a saw, H, or other convenient or desirable pruninginstrumentmay be adapted to the handle D; every suchinstrumentbeingprovided with a neck and disk, like C and c. The chopping-blade Amay be usefully employed in clearing away brushwood, cuttingcorn-stalks, tobacco, Sto.

Having described my invent-ion,- whatIclaim as new is- An implement forpruning trees, &c., composed of a handle, D E, provided with a recessedseat, e, as described, combined with a blade provided with a shank, C c,iitted to said seat, as described, and for the purpose set forth.
